Potentially Explosive Environments - Snom M9 Schnellstartanleitung

SELV (Safety Extra Low Voltage) Compliance
Safety status of Input/Output connections comply to SELV requirements.

Potentially explosive environments

Switch off your device when in any area with a potentially explosive
atmosphere and obey all signs and instructions. Sparks in such areas
could cause an explosion or fire resulting in bodily injury or even death.
Switch off the device at refuelling points such as near gas pumps at
service stations. Observe restrictions on the use of radio equipment in fuel
depots, storage, and distribution areas; chemical plants; or where blasting
operations are in progress. Areas with a potentially explosive atmosphere
are often but not always clearly marked. They include below deck on boats,
chemical transfer or storage facilities, vehicles using liquefied petroleum
gas, and areas where the air contains chemicals or particles such as grain,
dust, or metal powders.
Sensitive Electronic Equipment
The current state of research concludes that operational DECT phones
normally do not adversely affect electronic equipment. Nevertheless, you
should take some precautions if you want to operate DECT phones in the
immediate vicinity of such equipment like sensitive laboratory equipment.
Always keep a minimum distance of 10 cm (3.94") to the equipment even
when the phone is in standby.
Electrical Surges
We recommend the installment of an AC surge arrester in the AC outlet to
which this device is connected to avoid damage to the equipmen t caused
by local strikes of lightening or other electrical surges.

Warning: To avoid electric shock, do not connect safety extra-
low voltage (SELV) circuits to telephone-network voltage (TNV)
circuits. LAN ports contain SELV circuits, and PSTN ports
contain TNV circuits. Some LAN and PSTN ports both use RJ-
45 (8P8C) connectors. Use caution when connecting cables.
